CUTTER OR KNIFE FOR CALF-DEHORNERS.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Application filed March 7,1906. erial No- 304,750.

To all whom't't may concern:

Be it known that CARL ZOELLER and JOHN Honors, citizens of Australia,residing at 296-298 Queen street and 275-277 George street,respectively, both in Brisbane, in the State of Queensland, Commonwealthof Australia, have invented new and useful Improvements in Cutters orKnives for Galf-Dehorners, of which the following is a specification.

This invention relates to instruments for dehorning calves, the objectbeing to obtain better results.

With the dehorners at present in use, the horn is cut by a flat blade,but it frequently happens that the root or stump shoots again and a newhorn grows. We have found that, by taking out the horn at its socketthere is not the same tendency for the horn to grow again, and havetherefore devised an improvement in the knife which enables it to carryout that object.

In carrying out our invention we construct the dehorner much on the samelines as those at present in use, viz: by providing in a suitable framea sliding cutter or knife operated by levers or racks, but with a viewto cutting into the root or socket of the horn we make the cutter orknife dished or bellied instead of flat.

In order that our invention may be better understood, we will now morefully describe same with the aid of the accompanying drawings.

Figure 1 is an elevation of a dehorner, illustrating our invention. Fig.2 is a section of same. Fig. 3 is a transverse elevation of the cutterhead and cutter. Fig. 4 is an elevation showing a modification of thecutter or knife and cutting head (the knife being show open). Fig. 5 isa section of same.

A is a frame (of metal) of sufficient size to allow it to be placed overthe horn. This frame is made, preferably, of two parts secured togetherso that a groove is formed therein, and at the top thereof a stationarycutter or knife B is secured while a movable cutter or knife 0 isallowed to slide up or down in the lower portion thereof. These cuttersor knives B.

G are dished or bellied as shown and are provided with cutting edges atB C.

The lower cutter or knife C may be operated in any desired manner, suchas shown in the drawings, by means of bell crank levers D and links E,or by other suitable means.

It will be understood that the cutting edges B G of the cutters orknives B, C, need not necessarily be transverse to the center line ofthe appliance but may be diagonal as in Figs. 4 and 5. Also, if desired,the stationary cutter or knife B may be removed, and instead thereof theupper end of the frame A may be dished or bellied and provided with aslot to permit of the cutter or knife 0 (having a transverse or diagonalcutting edge) sliding therein, the horn in this case being cut againstthe upper end of the frame A.

Our appliance may be operated in the same manner as those at present inuse excepting that prior to bringing the cutters or knives B, Gtogether, they must be Well pressed down towards the root or socket ofthe horn.

Having now particularly described and ascertained the nature of our saidinvention and the manner in which it is to be performed, we declare thatwhat we claim is:- v

A device for dehorning; cattle comprising a frame, a sta tionary bladein said frame, a blade mounted to slide in said frame towards and fromthe stationary blade, each of said blades having a dished section sothat their cutting" edges are to one side of the plane of the frame,handles pivoted to opposite sides of said frame and having inwardlyextending portions, and links connecting said inwardly extendingportions with the slidable blade.

Dated this second day of February 1906.

In testimony whereof they have signed their names to this specificationin the presence of two subscribing wit- HQSSGS.
